Have others add text to a html page

ok i got a html page… is there any script out there or a way to let others connect to a secure area and use a script which allows them add text to a current html page?

i ain’t using frames, but let’s say we use it…

u got page a) b) and c)

page b) contains … let’s say ‘site news’

is there any way i can have a friend (which also is running my site) connect to a secret page where he can enter something and have it added to page b) ? almost like with post or phpnuke… but i don’t wanna run them… needs to be html…

is there a html way to do this? together with a php or javascript or something?
